APPARATUS FQR TREATING IRON.

SPECIFICATION forming part of Letters Patent No. 771,220, dated October4, 1904. Application filed February 16, 1903. Serial No. 143,691. (Nomodel.)

To all whmn it may concern:

Be it known that 1, JAMES WALTER ARNOLD, a citizen of the United States,residing at the city of Covington, in the county of Kenton and State ofKentucky, have inventedcertain new and useful Improvements in Apparatusfor Treating Iron; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improved apparatus for treating iron or steel.

One of its objects is to provide apparatus whereby the hot iron from themuck-rolls may be delivered direct to the reheating-furnace while stillhot.

Another object is to provide means for automatically feeding thereheated metal to the finishing-rolls.

Another object is to provide means Whereby the hot bars from themuck-rolls may be weighed and out into sections before being reheated.

Another object is to provide an improved furnace for reheating themetal.

It also consists in certain details of form, combination, andarrangement, all of which will be more fully set forth in thedescription of the accompanying drawings, in which Figure 1 represents aside elevation of my improved apparatus in position for use. Fig. 2represents a top plan view of the same. Fig. 3 is a horizontal sectionalview through the furnace on line 1) o of Fig. 1. Fig. 4:15 a detail ofthe mechanism for weighing the bars before cutting into sections. Fig. 5is a vertical section through the charging-door. Fig. 6 is a detail ofthe finishing-rolls and conveyer thereto.

The practice heretofore has been to allow the bars from the muck-rollsto cool and after which they are cut into sections and fed by hand to areheating-furnace and then by hand to a set of finishing-rolls. By myimproved apparatus the hot bars from the muckrolls are delivered upon aset of power-driven rolls A, by means of which they are brought to aposition above the scales A. Upon throwing the lever a the bars B of thescaleshears C, which cut the bar into sections of suitable length to befed to the reheatingfurnace D. These sections or billets as they leavethe shears drop upon an endless belt or apron E, passing over the idlerolls 0 e c and being driven by power applied to shaft F. This beltcarries and delivers the billets to an automatically-operatedcharging-door G. This door may be located in the side wall of thefurnace, but is preferably located in the crown of the furnace, as shownin Fig. 1. The door is pivoted at g and weighted, so as to normallyclose the opening 0. \Vhen the billets are deposited on the door,however, it automatically opens and permits the bar to drop onto thehearth H. The hearth is preferably composed of a rigid section It,adapted to withstand without injury the impact of the billets, and oneor more sections it of loose friable material upon which the billets aredisposed until sufficiently heated to be passed to the finishing-rolls.

1 represents a series of rolls driven by power through a chain belt Iand supported in a frame J. When the billets are sufliciently heated,they are withdrawn through the doors K and placed on the rolls I, bymeans of which they are fed to the finishingrolls I.

M represents the stoking door, through which the furnace-fire ismaintained.

N represents the grate, and N the fire-bridge .of ordinary construction.It is obvious that my improved apparatus, while particularly adapted forcharging and treating hot bars direct from the muck-rolls, may also beemployed to advantage in charging cold bars into the furnace; also,thatthe mechanism shown is capable of considerable modification withoutdeparting from the principle of my invention.

Having described my invention, what I claim is-- 1. In aheating-furnace, a charging-passage, a door normally closing saidpassage, and

adapted to automatically open to deposit the metal delivered theretoupon the hearth, and to again close the passage; and a power-drivencarrier adapted to carry and deliver the metal to the charging-door.

2. An apparatus for treating iron interposed between the muck-rolls andthe finishing-rolls, consisting of feeding-rolls to convey the barsdirect from the muck-rolls, shears to sever the bars so conveyed intosections, a conveyer to convey and discharge said sections into thereheating-furnace, a reheatingfurnace, and rolls between said furnaceand the finishing mechanism, whereby the metal is advanced from themuck-rolls to the finishing mechanism without substantial loss of itsoriginal heat.

3. An apparatus for treating iron, interposed between the muck-rolls andthe finishing-rolls, consisting of feeding-rolls to convey the bars fromthe muck-rolls, scales to lift the bars from said rolls to weigh thesame, shears to sever the bars so conveyed and weighed into sections, aconveyer to convey and discharge said sections into thereheating-furnace, a reheating-f urnace, and rolls between said furnaceand the finishing mechanism, whereby the metal is advanced from themuck-rolls to the finishing mechanism without substantial loss of itsoriginal heat.

' vey the bars direct from the muck-rolls, scales to lift the bars fromsaid rolls to weigh the same, shears to sever said bars into sections, aconveyer to convey and discharge said sections into thereheating-furnace, and a reheating furnace, whereby the metal from themuck-rolls is advanced through the reheatingfurnace to the finishingmechanism without substantial loss of its original heat.

In testimony whereof I have signed my name in the presence of twosubscribing witnesses.

. JAMES WALTER ARNOLD.
